blazed, if you have old maps from before entrenchment that you want to play then my map updater v2.01 will correctly update ANY map from any map version to map version 3(sins 1.15+/entrenchment 1.01+/diplomacy) and for entrenchment 1.01 the galaxy manifest maker will create a NEW galaxy.manifest with all the maps in the program files galaxy folders and the correct count of galaxy's at the top of the file so that entrenchment 1.01 can offer all the maps in the small/medium/large maps ( the size is determined by the sins engine first by number of players, then number of GravityWells in the map).
here is a quick guide outline for entrenchment 1.01 (only) map adding
1 put map(s) in the program files\stardock games\sins of a solar empire\galaxy folder
2 run my galaxy manifest manager
3 click on the button 'auto-fix galaxy.manifests' (the second button on the top row)
4 click on exit ( the rightmost button on the second row)
5 start entrenchment 1.01, start a new game look through the map lists for the map you want to play, select the map and play
hope this helps
